TIRE-HEATING DEVICE.

SPECIFICATION forming part Of Letters Patent N 0, 737,034, dated August 25, 1903.

Application filed January 15,1903. Serial No- 139,1l3. (N0 model.)

To all whom it may cortcern:

Be it known that I, CHRISTOPHER SoLBnRe, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Tire Heating Devices; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains'to make and use the same. V

My present invention relates to tire-heating devicesand is in the nature of an improvement on the device disclosed and claimed in myprior patent, No. 692, 37 6, of date February 4, 1902, entitled Tire-heating device.

The objects of mypresent invention are to improve in point of efficiency the tire-heating devices disclosed in my said prior patent.

To the-above ends the invention consists of the novel devices and combinations of devices hereinafter described,and defined in the claims.

The inventionis illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a central vertical section show ing the tire-heating device constructed in accordance with my invention. Fig. 2 is a plan view of the device with some parts broken away and others removed. Fig. 3 is a plan view of one of the twyers or burners removed from the device and some parts beingsectioned. Fig. 4 is avertical section on the line 00 m of Fig. 3, and Fig. 5 is a detail in end elevation of one of the tire-supporting brackets. i

The numeral 1 indicates a hollow, body,

which is supported by legs 2, and rising from the central portion of which is a tubular standard 3, communicating therewith and provided at its upper end with an oil tank or reservoir 4. In the lower end of the tubular standard 3 is a valve-seat 5, which is adapted to be opened and closed by aneedle-valve 6,the stem of which is passed upward through said standard andthrough said tank 4 andhas screwthreaded engagement with thebearing 7 on the top of said tank and is provided with a handwheel 8, by means of which said valve may be operated at will.

sage or perforation 22".

The lower ends of a ra outer endof a stub-tube-lfi, which is bent laterally or:offset, as shown in Fig. 2, so as to clear the corresponding lug 10, and is then screwed into the body 1. The inner end of each tubular section 15 communicates with a port 17, leading into the interior of said body 1. The several ports 17 are adapted to be simultaneously opened and closed by a perforated annular ring 18, seated within the said body 1 and having teeth which mesh with a pinion 19, the shaft 20 of which projects upward through the top wall of said body 1. and is provided with a handpiece 21.

The upper and outer end of each oil-tube 14 passes directly through a cooperating hollow head 22, which constitutes the generatingchamber of the twyer. At their sides the heads 22 are provided with trunnions 23, which Work freely in slots 24, formed in the prongedfree ends 25 of the supporting-arms 9. At their inner sides the heads 22 are constructed and provided with an inwardly-diverging entrance-passage 22, while on their tops they are provided with a gas-escape pas- The delivery ends of the gas-tubes 14 are bent inwardly and downwardly and terminate in discharge-nozzles 26, that stand in position to discharge directly into the diverging passages 22 of the heads 22. Oil-cups 27, which are opened at their sides adjacent to the heads'22, are suitably secured to the oil-pipes 14 in positionto receive oil drippings from the nozzles 26. On each head 22 is rigidly secured a tireholder or rest-bracket 28, having laterallyspaced and shouldered rest-lugs 28, whichare adapted to support the tire just above the perforations 22 of the heads 22.

Operation: As is evident, by adjusting the too nut 11 vertically the supporting-arms 9 will be simultaneously adjusted so as to throw the rest-brackets 2S and thetwyer-heads 22 nearer to or farther from the standard 3, keeping the same, however, always on the line of a circle which is concentric to said standard. In this way the device may be adjusted to tires of different sizes. In my prior patent the gas was generated at the part corresponding to the body 1, but in my present invention the gas is generated at the twyers. In starting the generation of gas oil is dripped into the cups 27 and is lighted in much the same manner as an ordinary gasolene stove. \Vhen the generation is once started, the burning gases within the heads 22 will produce sufficient heat to continue the generation of gas in the sections of the oil-tubes Mwhich pass through said head. The burning gases, escaping through the perforations 22 will be directed onto the tire supported on the rest-lugs 2S" oi' the brackets 28. As the rest-brackets and the heads of the twyers are adjusted together, they are of course always kept in the proper relation to each other to properly direct the flames on the tire supported by the device.

hat I claim, and desire to secure by Letters Patent of the United States, is as follows:

1. In a tire-heatingdevice, the combination with radial supporting-arms, of hollow heads and tire-seats carried at the free end of said arms, said seats being above said heads, said heads having lateral inlet-passages and vertical outlet-passages, the latter being positioned to direct the flame in vertical line with said tire-seats, and oil-delivery tubes passed vertically through the said hollow heads and provided with discharge-nozzles positioned to discharge into said heads through the lateral inlet-passages thereof, substantially as described.

2. In a device of the character described,

the combination with hollow heads 22, having diverging inlet-passages 22, and dischargeperforations 22 of the tire-rests on said heads positioned to support the tire above said perforations 22 and the oil-delivery tubes 14, passed through said heads 22 and bent downward and terminating in nozzles 26 positioned to discharge into said inlet-passages 22, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

CHRISTOPHER SOLBERG.
